Answer:
below
Step-by-step explanation:
add -36 to both sides
divide both sides by 2
This is a quadratic equation
let's solve it by graphing it
The solution are the x-coordinates of the intersection points
The x-coordinates of the intersection points are approximatively -1.6 and 5.6
Answer:
X=16
Step-by-step explanation:
10x-8=9x+8
First you have to simplify.
10x-9x=1x
So now the equation looks like this
x-8=8
Now you have to get x by itself
-8+8=0 and we have to do the same thing on both sides of the equal sign 8+8=16
The equation now looks like this x=16
And that's your answer
Answer:
Step-by-step explanation:
The question is:
The amount of red blood cells in a blood sample is equal to the total amount in the sample minus the amount of plasma. What is the total amount of blood drawn? Red blood cells = 45% Plasma = 5.5 ml
Solution:
We have given:
The amount of red blood cells in a blood sample is equal to the total amount in the sample minus the amount of plasma. We need to find how many ml is 1% of blood.
The equation we get is:
Red blood cells = total sample - amount of plasma
45% = 100% - 5.5 ml
Combine the percentages:
5.5 ml = 100%-45%
5.5 ml = 55%
0.1 ml = 1%
1% = 0.1 ml
Now you can find out red blood cells volume or total sample volume.
Red blood cells volume = 45% x 0.1ml/%
= 4.5ml
Total sample volume =100% x 0.1ml/%
= 10ml .
Let her total earnings = y (dependent variable)
and her hours worked = x (independent variable)
y = 18x + 75
Answer:
Square root of 65 units.
Step-by-step explanation:
Length of the other leg = sqrt(9^2 -4^2) (By Pythagoras),
= sqrt(81-16)
= sqrt65
